Abstract
A system and method for performing a security check at a checkout terminal is disclosed. Various heuristics are utilized to verify that a customer or clerk has properly identified an item being purchased. In various embodiments, the weight or other physical characteristics of an item placed on a product scale are measured and compared with expected physical characteristics for the item. If a mismatch is detected between the actual physical characteristics and the expected physical characteristics, the transaction may be flagged for further investigation.
